Stress

The process by which we perceive and respond to certain events, called stressors, that we appraise as threatening or challenging.

Is a process of perceiving and responding

The response is called a stress reaction.

General Adaptation Syndrome

The body’s adaptive response to stress in three phases

Alarm Reaction – nervous system activated in response to stressor
Resistance – body responds with physiological reactions to cope with the stressor
Exhaustion – body’s resistance to stress is depleted (physical deterioration)



Perceived Control
The sense of control or influence one has over stressful events in one’s life
Most studies suggest the lower the perceived control the larger the potential for health-related problems
Lower perceived control leads to a lowered immunity to disease.

Optimism

A generally positive outlook on the future

Optimists have stronger immune systems and recover faster from health problems.

Stress Hormones
Hormones released in response to stress
The body must work to rid the body of the stress hormones.
Pessimism and perceived lack of control both produce more stress hormones.
